Using four jack stands. How?

+1 on DavesZ#3 mentioning the usage of ramps to access the center lift point. If you don't have any ramps, try what I do:
Whenever I do my oil changes, I jack up the car from one side (positioning the jack behind the front tire), and then once the car is lifted up, I put a jackstand at the frame support thingy (not the outer edge near the rail thingy).
Then I get my jack and find the center jacking point and jack the car up so both front tires are off the ground. I am then able to position the other jackstand on the opposite side.
As you can see from these pics below, I have my jackstands towards the inside of the car supporting the inner frame. They're not on the outer edge rail thingy. The car is firm and is safe on this setup.

what do you guys think? it was very stable and actually pretty easy after following some of your tips. i picked these spots because of their thickness and, from the looks of it, these points support a lot of the weight while the car is on the ground. thoughts?

It would be "less bad" if you where using the flange instead. But not much.
If the area where you're lifting deforms, you'll have created a hinge where the whole floor can bend. If you're tracking your car, you don't want that kind of things.
Just so you know I'm not making this up: I'm a body designer. I design unibodies for a living. Jacking the car to far from the jack points is not a good idea.

It's my considered opinion that you want the largest, thickest pieces of metal under there resting on the stands. There are a couple of places under there that look great to me. N1ck! showed a couple of them. I'd use suspension points and areas of subframe long before I'd consider the sheet metal under the doors. Where the subframe meets the body is a strong area, too. Where I put the stands depends on what I'm going to do under there. It's good to have some choices so the stands aren't in the way.

I dont own a Z...but I own a relatively low 240sx and when me and a friend did my TC bushing install, we used ramps and a jack...it was SO NICE and quick...

thank you everyone so far for your inputs. i just got those rubber boots a copule of days ago, and they were a good idea! they are made of thick plastic/rubber and it actually makes the support point a little wider. not bad for about $15. hey, and harbor freight is also have a sale on that blue aluminum racing jack. it's really light, and a pretty reputable shop here in so cal has been using one for about 3 years and has had no problems with it (as far as leaks, etc).

Hey Dave, I haven't been under the car much...but where is the center lift point in the front? I've been struggling with how to get the front on Jackstands for a long time.

Here you go. It's the black, odd shaped piece with the 2 large bolts, right behind the oil cooler (which is the APS finned cooler on mine)

Look at the pic of the black and orange jack stand in post #12 from Kolia. You can do that in all four "corners".
